Others

Presses

Sample calculation saving 225.000 kWh per Year

Originally required power: ~ 900 kW

Storage power: 450 kW (LES 300)

Peak power: LES 300: + 350 kW / - 460 kW

RMS power:~ 250 kW

Total lifetime: 53,700 hrs / 10 years (average)

The exchange of a mechanical storage through an electric storage results in an elimination of downtimes through services as well as noise

Passenger and freight elevators

The Liduro Energy Storage provides for power supply during switching or peak shaving.

Ultracapacitors

Liduro Energy Storage – LES 300: The scalable Liduro Energy Storage systems for stationary and mobile applications are characterised by a high power density. With their compact dimensions, they can easily be integrated in applications with limited space:

Technology: Ultracapacitors / Liquid-cooled

Energy content: 690 – 4,140 kJ

Power output: 100 kW / 200 kW

Dimension (W / D / H): 800 / 600 / 2,000 mm

Scalable system

The LES 300 can be scaled within its cabinet: Energy contents from 690 kJ to 4140 kJ are possible as well as power outputs of 100 kW or 200 kW.

Both systems, the LES 300 and LES 200, can be connected in parallel up to ten times.

The System includes:

Storage units
Converter unit
Cooling
Control

Power density and safety

Liduro Energy Storage – LES 200: The systems have well thought-out protection concepts: In the event of a fault, an isolating unit with fuses and switching contacts separates the storage from the power supply.

The housing of the LES 200 combines utility and design. Dust and water do not pose any problem. The connection unit of the power cables and the plug interfaces are correspondingly sealed, this allowing both indoor and outdoor operation.

Technology: Ultracapacitors / Liquid-cooled

Energy content: 1,500 kJ

Power output: 100 kW

Dimension (W / D / H): 750 / 1,120 / 1,100 mm

Liebherr, durable and robust – Liduro

Reliability and application safety: The highly efficient storage and reuse of recuperation energy provides for maximum reliability and operational safety during network fluctuations and prevents applications from malfunctions related to the network supply.

Low2no maintenance: The Liduro Energy Storage system is a low2no maintenance product based on its design, quality and protection concept. It is water-cooled and hardly includes wearing parts.

Easy integration: The mechanical and electrical integration of the complete system in an application is easy: Including the storage, converter, controlling and cooling units, only the electrical power cables as well as the power supply and cooling need to be connected.
